Technical field
The present invention relates to a kind of plasma display panel (hereinafter being called " PDP "), and relate in particular to a kind of PDP, and drive the method and apparatus of this PDP.
Background technology
PDP is adapted to pass through luminous fluorescent material and uses the ultraviolet ray that produces in the discharge process of inert mixed gas such as He+Xe or Ne+Xe to come display image.This PDP is easy to make thinly and is big, and because recent development of technologies, this PDP can provide significantly improved picture quality.Particularly, because the wall electric charge is gathered on the surface and the protected sputter that prevents owing to the discharge generation of electrode when discharge, 3 electrode A C surface discharge type PDP have low voltage drive and long advantage of life-span.
Fig. 1 is the stereogram of structure of the discharge cell of the traditional 3 electrode A C surface discharge type PDP of expression.
Referring now to Fig. 1, this 3 electrode A C surface discharge type PDP comprises a plurality of scan electrode Y on the bottom surface that is formed on upper substrate 10 and a plurality ofly keeps electrode Z, and is formed on the addressing electrode X on the infrabasal plate 18.
The discharge cell of this PDP forms each and crosses scan electrode Y, keeps electrode Z and addressing electrode X, and is aligned to matrix shape.
Each scan electrode Y and keep electrode Z to comprise that a transparency electrode 12 and one have live width than transparency electrode 12 little and be set at the metal electrode 11 of this transparency electrode one side.
Usually this transparency electrode 12 of being made by ITO (indium tin oxide) is formed on the bottom surface of upper substrate 10.Usually this metal bus electrode 11 that is made of metal is formed on the transparency electrode 12 and is used to reduce the voltage drop that is caused by the transparency electrode 12 with high impedance.Wherein be provided with scan electrode Y and keep on the bottom surface of upper substrate 10 of electrode Z and covered by last insulating barrier 13 and protective layer 14.Should go up insulating barrier 13 and gather the wall electric charge that in the plasma discharge process, produces.This protective layer 14 is used for preventing going up insulating barrier 13 because sputter damage electrode Y that the plasma discharge process causes and Z reach, and improves the efficient of secondary.Magnesium oxide (MgO) is used usually as protective layer 14.
This addressing electrode X is with scan electrode Y with keep on the direction that electrode Z intersects and be formed on the infrabasal plate 18.Fluorescence coating 16 is applied to down on insulating barrier 17 and the dividing plate 15.It is ultraviolet ray excited to produce in redness, green and the blue visible light line any one that this fluorescence coating 16 is produced in the plasma discharge process.
Inert mixed gas that is used to discharge such as He+Xe, Ne+Xe or He+Xe+Ne are injected in the discharge space that is arranged on the discharge cell between upper substrate and infrabasal plate 10,18 and the dividing plate 15.
Fig. 2 is illustrated in the traditional frame that comprises eight subdomains of method that is used for driving traditional PDP.
With reference to Fig. 2, this 3 electrode A C surface discharge type PDP are driven in such a way, promptly for the gray scale that realizes image a frame are divided into the subdomain of several different emitting times.As shown in Figure 2, if use 256 gray level expressing images, the frame period (16.67ms) that is equivalent to 1/60 second is divided into 8 subdomain SF1 to SF8.Subdomain SF1 each in the SF8 is divided into the reset period that is used for the initialization discharge cell, is used to select the addressing phase of discharge cell, and is used for realizing keeping the phase of gray scale according to discharge count.SF1 is identical to the reset period of each subdomain of SF8 with the addressing phase, yet the phase of keeping of each subdomain and its discharge count are with 2 nThe ratio of (n=0,1,2,3,4,5,6,7) increases.
Yet, the very difficult addressing phase that at random reduces PDP.Therefore,, so just such problem is arranged, be difficult to exactly guarantee fully to keep the phase if increase subdomain to increase the noise profile in resolution or the minimizing animation.
For example, be 3 μ s if be used to address the time of discharge, the essential addressing phase of a subdomain of the resolution of VGA 640 * 480 is 3 μ s * 480=1.44ms.In addition, if the needed reset period of each subdomain is approximately 300 to 600 μ s and eight subdomains are included in the frame period (16.67ms) as shown in Figure 2, necessary reset period and the summation of addressing phase are (1.44ms * 8)+((0.3 to 0.6ms) * 8)=13.92 to 16.32ms in the frame of the resolution of VGA grade.Therefore, remove reset period and addressing phase, the phase of keeping is 16.67ms-(13.92 to 16.32ms)=0.35 to 2.75ms, and this only is equivalent to 2.09 to 16.5% of a frame period.
If resolution becomes XGA 1024 * 768, a necessary addressing phase of subdomain is 3 μ s * 768=2.3ms so.If be used for the reset period of a subdomain approximately is that 300 to 600 μ s and eight subdomains were included in the frame period of XGA resolution, and an interior reset period and the summation of addressing phase of frame period is 2.3ms * 8+ ((0.3 to 0.6ms) * 8)=20.8 to 23.2ms so.Therefore, except reset period with the addressing phase, the phase of keeping is that 16.67ms-(20.8 to 23.2ms)=-6.53 arrives-4.13ms.If eight subdomains are assigned in the frame of XGA grade, under the situation that does not reduce the time that is used to address discharge, be difficult to so guarantee to keep the phase.
In order to solve the deficiency of driving time, the someone has proposed a kind of method, and wherein PDP is divided into the upper and lower, and this upper and lower all is double scanning (double-scanned).This double scanning method has a shortcoming, promptly because data must offer the upper and lower of PDP respectively, so need about 2 times data drive circuit.
Therefore, traditional PDP guaranteed to keep the phase because of very long being difficult to of addressing phase.Thereby, so exist because brightness is low and quantity subdomain can not be expanded the noise profile sensitive issue in the animation.
Below with reference to Fig. 1 traditional well type diaphragm structure is described in detail.
Fig. 3,5 and 7 is plane graphs of the well type diaphragm structure of the traditional surface discharge type AC plasma display panel of expression.Fig. 4,6 and 8 is expressions when comprising Fig. 3, bus electrode just is placed on the plane graph on the horizontal baffle during 5 and 7 diaphragm structure.
At first well type dividing plate is described with reference to Fig. 3.This dividing plate comprises a plurality of horizontal baffle 211a that form by horizontal direction, 211b and 211c and a plurality of vertical partition plate 212a that forms by vertical direction, 212b and 212c, to prevent at adjacent unit 213a, produce erroneous discharge among 213b and the 213c, horizontal baffle and vertical partition plate are set on the lower glass substrate (not shown).In other words, this well type dividing plate has unit 213a, and 213b and 213c be by horizontal baffle 211a, 211b, 211c and vertical partition plate 212a, the shape that 212b and 212c surround.
With reference to Fig. 4, transparency electrode 215a and 215b are set on the unit.Bus electrode 214a and 214b and horizontal baffle 211a, the top of 211b and 211c is spaced a distance and is set at this horizontal baffle 211a, the both sides of 211b and 211c one by one.
Yet in having the surface discharge type AC PDP of above-mentioned well type diaphragm structure, the zone that luminous energy passes through accounts for each unit 213a, the ratio of the area of 213b and 213c, and this is an important elements of decision brightness, that is, and the aperture ratio is quite low.Therefore, this PDP has brightness and inefficient problem.
In order to address this problem, the PDP with the well type diaphragm structure shown in Fig. 5 or 6 is suggested.Also promptly, in Fig. 5 or 6, horizontal baffle 221a, the width of 221b and 221c is than the horizontal baffle 211a shown in Fig. 3 or 4, and 211b and 211c are thick.
Yet, in PDP, so because the capacitance between data electrode (not shown) and the upper electrode increases invalid electric work increase with diaphragm structure as shown in Fig. 5 or Fig. 6.For this reason, the problem that has the power consumption increase of whole front panel.
In order to address the above problem, the PDP that has as Fig. 7 or diaphragm structure shown in Figure 8 is suggested.In Fig. 7 or Fig. 8, have given width and height of level groove 236a, 236b and 236c are formed on the horizontal baffle 231a shown in Fig. 5 or Fig. 6 by horizontal direction, on 231b and the 231c.
It can be seen from the above, and Fig. 6 comprises bus electrode and transparency electrode with Fig. 8 in the identical mode of describing among reference Fig. 4, has simultaneously as Fig. 5 and diaphragm structure shown in Figure 7.
In the PDP that has as Fig. 7 or diaphragm structure shown in Figure 8, thereby because the capacitance between upper electrode and the lower electrode reduces invalid electric work reduces.In addition, because groove as passing away (exhaust passage) discharging performance also be enhanced.Yet, thereby the capacitance between the lower electrode and upper electrode still keeps very high on the dividing plate because bus electrode is set at.
And, the typical diaphragm structure of this PDP comprise as shown in Figure 9 bar shaped and connecting-type as shown in figure 10.Fish-bone as shown in figure 11 (Fish Bone) type also has been developed at present.
Bar shaped dividing plate 15 as shown in Figure 9 only is being formed on the direction of addressing electrode X between the addressing electrode X, thereby physically separates adjacent in the horizontal direction discharge cell.The advantage of in the space between the adjacent unit of vertical direction is not closed the discharge process at PDP easily, discharging thereby bar shaped dividing plate 15 has.Yet bar shaped dividing plate 15 has because apply the area of fluorophor very little and reduced the brightness of PDP and the shortcoming of efficient.
On the contrary, connecting-type dividing plate 45 as shown in figure 10 is formed between the addressing electrode X according to the direction identical with the addressing electrode.Connecting-type dividing plate 45 comprises the vertical partition plate 45b of the discharge cell that physically separation is adjacent in the horizontal direction, and is formed between the vertical partition plate 45b physically to separate the horizontal baffle 45a at the adjacent discharge cell of vertical direction.
This connecting-type dividing plate 45 has the zone advantage wideer than bar shaped dividing plate that applies fluorophor, thereby but since dividing plate almost closed passing away with vertical direction in the horizontal direction respectively and had the very difficult shortcoming of discharge in the discharge process of PDP.
Fish bone well dividing plate 55 as shown in figure 11 comprises the vertical partition plate 55b that forms according to the direction identical with addressing electrode X between addressing electrode X, physically to separate adjacent in the horizontal direction discharge cell; With at the horizontal baffle 55a that in each vertical partition plate 55b, forms on the vertical direction of vertical partition plate 55b, thereby make passing away be formed on the center, thereby physically separate at the adjacent discharge cell of vertical direction.
It is wideer and compare the advantage of easy assurance passing away with connecting-type dividing plate 45 than bar shaped dividing plate 15 that this fish bone well dividing plate 55 has the coated area of fluorophor.
Yet though adopt diaphragm structure as shown in FIGS. 9 to 11, aforesaid PDP exists its efficient not reach the problem of satisfied level.And, if the amount of Xe increases to improve resolution or efficient in discharge gas, so just have the addressing discharge and be delayed, promptly address the jitter value increase so that the problem that driving time shortens.If the addressing discharge delay time is elongated, elongated and phase of keeping phase that addresses so shortens so much.Therefore be difficult to separate or increase subdomain reduces picture quality such as noise profile with minimizing factor.
And aforesaid PDP is because metal bus electrode 11 is crossed the effective display surface in discharge cell, thereby because metal bus electrode 11 exists the aperture than problem low and that brightness is lowered.
